Review all safety warnings on Page one of your garage door operator owner's manual. Ensure that the
door and all its operating gear is in good condition and works easily when it is manually operated.
Balance Test
Lift the door about halfway. Release the door. It should stay in place,
supported entirely by its springs.
Raise and lower the door to see if there is any binding or sticking. If
your garage door binds, sticks or is out of balance, call a professional
garage door service engineer.
Lubricate all garage door working parts before installing the door arm. Ensure that the timber or metal garage
door frame on both sides and above the door is in good and sound condition and is securely fixed to the main
structure of the garage. If there is any doubt, consult a professional garage door installer. (See the Yellow Pages
under Garage Doors)
Do not run the operator until installation is complete.
